Provided is a film containing a polycarbonate resin which has excellent draw-down resistance during thermoforming and which which can achieve excellent moldability in processing in curved parts and the like. The film contains a polycarbonate resin (a) which satisfies the formula (i), where the viscosity at a shear rate of 6.080 * 10 [1/s] measured at 300 DEG C is defined as X [Pa*s], and the viscosity at a shear rate of 6.080 * 103[1/s] measured at 300 DEG C is defined as Gamma [Pa*s]. 本发明提供一种含有聚碳酸酯树脂的膜，该膜在热成型时抗下垂性优异，并且在加工弯曲部等时能够实现优异的成型加工性。该膜含有聚碳酸酯树脂(a)，该聚碳酸酯树脂(a)在将以300℃测得的剪切速度6.080×10[1/s]时的粘度设为X[Pa·s]，并将以300℃测得的剪切速度6.080×103[1/s]时的粘度设为Y[Pa·s]时，满足下述式(i)：
